Exiled Redoubt

Skeletal Protector

All: At 50% and 30% health he becomes immune and spawns Skeletal Protectors, two at 50% and three at 30%. Kill them to continue.

Shield Charge

All: Stay close to him, even as a ranged character, or he charges at you.

Shield Throw

All: Dodge roll or block Shield Throw. It hits twice, once thrown and once on the return.

Skeletal Archers and Sorcerers

Tank: Pull the small Skeletal Archer and Sorcerer adds to the boss so they die to cleave.

Laceration

Tank: Block Laceration, her axe cone attack. It deals little damage when blocked.

Shadow Cleave

Tank: Block or fully avoid Shadow Cleave's lane effect; it deals heavy damage.

Death Knell

All: Death Knell hits everyone and applies a Condemn damage-over-time effect. Cleanse it if you can.

Swirling Darkblades

All: Move out of Swirling Darkblades before it fully expands and drops.

Execute

All: Stack inside the yellow Execute circle with everyone else. This divides the jump damage so nobody dies alone.

Spike Traps

All: Avoid or dodge roll through Spike Traps. She triggers them at 75%, 50% and 30% health, plus smaller random ones, and they leave a bleed.

Albus Torturer and Jailer add phase

Tank: Interrupt the Albus Jailers.

Dps: The boss is immune while adds are alive, at 75%, 50% and 30% health. Kill them quickly and avoid the Torturers' frontal cone.

Soul Shatter

Tank: Move out of Soul Shatter's effect. Its damage increases each tick and can eventually kill even a tank outright.

Animate Thrown Objects

All: Dodge the flying haunted object marked by a red circle above your head. It deals little damage but stuns and knocks you down.

Storm Bolt / Chain Lightning

All: Do not touch the Storm Bolt effect; touching it chains lightning to everyone.

Iron Charge

All: During Iron Charge the boss is immune and leaves fire effects while charging around. Stay out of his path.

Iron Atronach Spider adds

Dps: Bring the spawned Iron Atronach Spiders to Lucilla's Frozen Dome; it slows them and makes them take more damage.

Blackspine Curse

Healer: Heal through Blackspine Curse's heavy damage-over-time effect on whoever it is cast on after Iron Charge ends.

Racing Flames

All: Avoid the Racing Flames salamanders, or overheal through them if you cannot.

Lightning Rod Slam

All: Move off the attracted-lightning effects that spawn under everyone during Lightning Rod Slam; they stay in place.

Simulacrum adds

Dps: Kill Simulacrums, roughly 94,000 health, which spawn below 40%, immediately. Their ranged firebolts escalate and eventually become lethal.

Coruscating Orb

Healer: Catch the Coruscating Orb by stepping into its effect, taking one zap, then walk it slightly away from the boss so melee do not have to move.

Pool of Grief

All: Move off Pool of Grief immediately; it deals heavy damage.

Overwhelming Sorrow

All: Block, dodge or shield through Overwhelming Sorrow's 8-second uninterruptible barrage to ease the healing load.

Vicious Denial

All: Avoid the bouncing Vicious Denial effects; they apply a snare on top of moderate damage.

Shadowy Duplicate

Dps: Kill the Shadowy Duplicate, roughly 338,000 health, quickly when it spawns.

Echoing Pain

Tank: Stand still during Echoing Pain; the cone follows you.

Healer: Stand behind Eliana, out of the Echoing Pain cone that follows the tank.

Dps: Stand behind Eliana, out of the Echoing Pain cone that follows the tank.

Six Sword Assault

All: Watch for the safe gaps between the six telegraphed sword effects, or block Six Sword Assault. It also throws extra fireballs and creates a large discharge effect during the Fire and Storm phases.

Vortex

Tank: Hug the edge of Vortex's growing effect and block. It also drops small elemental effects during each phase (Hot Foot, Shocking Beam), so move off those.

Coordinated Slash

Tank: Block Coordinated Slash; do not dodge it, as dodging enrages the boss for 30% more damage. Blocking gives you Rattled (70% less damage done, 40% more taken) and Hindered (healing absorption), so call for heals.

Healer: Heal through Hindered on the tank after every blocked Coordinated Slash. It is a healing-absorption debuff that cannot be cleansed.

Fire Atronach / Fire Orb (Fire Phase)

Dps: Pick up the Fire Orb immediately after killing a Fire Atronach, at 95%, 90%, 80% and 70% health. It applies a 15-second Ignited damage-over-time effect to you, so only kill as many Atronachs as the healer can handle at once.

Fire Storm (Fire Phase)

All: Stand fully inside or fully outside each Fire Storm's circling path; it does not despawn for the rest of the fight.

Frost Atronach / Frost Orb (Frost Phase)

Dps: Wait for any active Ignited effect from a Fire Orb to expire before picking up a Frost Orb; the Fire and Frost effects explode if they touch. Pick it up immediately once safe (a 15-second Freezing Death effect).

Frozen Ground (Frost Phase)

All: At 55%, 35% and 5% health the arena edges freeze and temporarily shrink your space. Stay near the centre until it thaws.

Storm Atronach / Shock Orb (Storm Phase)

Dps: Pick up the Shock Orb immediately when it drops (a 15-second Storm effect). The same healer-pacing rule as the Fire and Frost Orbs applies.

Impeding Storm (Storm Phase)

Dps: Interrupt the Storm Atronachs' Impeding Storm cast.

Thunderstrike (Storm Phase)

All: Thunderstrike hits everyone and cannot be avoided, only mitigated. Do not stack on other players, stay still, and block or shield if you can.
